In 2002, The Robert Wood Johnson Foundation launched Children's Futures (CF), a 10-year community change initiative designed to improve the health and well-being of children from birth to age three throughout Trenton, NJ. CF's strategies included efforts to increase residents' access to prenatal and other health services, provide parenting skills education, improve the quality of available childcare and promote preventive healthcare among medical practices. The Foundation engaged P/PV to evaluate the implementation and outcomes of the initiative and to provide ongoing feedback on its progress. This report, and its forthcoming companion, Early Outcomes in a Community Change Effort to Improve Children's Futures, examine the promise of CF strategies. Collaboration and Community Change in the Children's Futures Initiative focuses on program implementation, participant recruitment and collaborations among Trenton's agencies. The second report examines programmatic improvements and early outcomes for CF families. Major findings from both are compiled in Children's Futures' First Five Years.
